About:
LibX11 is the standard client-side library for communicating with the X Window System using the X11 protocol. It provides the C language interface for applications to create windows, handle input events, and manage graphics contexts. This library is essential for running graphical applications on Unix-like systems that rely on the X11 architecture.
Key Features:
  • Implements the X11 protocol communication
  • Provides low-level window management APIs
  • Supports event handling and input processing
  • Standard library for X Window System applications
Use Cases:
  • Developing native graphical applications for Linux/Unix
  • Enabling GUI functionality for software running on X11 servers
  • Building window managers and desktop environments
Alternatives:
  • Wayland – Modern display protocol replacing X11, requires different client libraries
  • XCB – Lower-level, more modern alternative to Xlib with better threading support
